Between 2011 and 2012, Thailand’s southern highways carried more than just goods. They carried death—one poisoned cup of coffee at a time. Nirut Sonkhamhan, known as The Pickup Truck Killer, preyed on drivers, turning roadside rituals into traps. This episode unspools the method, the victims, and the poison trail he left in his wake, through the words of survivors, investigators, and the land itself.

This story draws from the reports of the Royal Thai Police, archival coverage in the Bangkok Post, Thai PBS, and Khaosod English, as well as local southern Thai press at the time. Survivor testimony from Montree Kalam, Charoen Daranoi, and Paitoon Pattalapho provided the most haunting details.

In the early evening of October 7, 2025, respected Nakhon Pathom businessman Rawi “Sia Piak” Arayawattanawech was ambushed outside his wife’s restaurant, Krua Dokmai Pa.
Two close-range shots—one to the torso, one to the head—left him in critical condition and launched one of the most intense provincial investigations in recent Thai history.

Police Region 7 quickly identified the attack as a contract hit tied to a 130-million-baht business conflict, a financial web involving quarry operations, heavy machinery, trucking, and long-standing networks of influence.
Within days, investigators traced the shooter, uncovered a former police officer allegedly involved in arranging the hit, and connected the attack to a deeper financial dispute.
But the true financier—the person who ordered the shooting—remains publicly unnamed.

This episode examines the events leading up to the ambush, the forensic trail left behind, the suspects identified, and the shifting power dynamics inside Nakhon Pathom’s business community.
A rare look into how money, reputation, and power collide in Thailand’s provincial underworld—and how a single act of violence can ripple across an entire city.

Am Cyanide, Sararat Rangsiwuthaporn, and the murder of Siriporn “Koy” Kanwong became one of the biggest Thailand true crime stories in recent memory after Koy died during a merit-making ritual at the Mae Klong River on April 14, 2023. In this episode of Shadows of Siam, we follow the cyanide evidence, the missing valuables, the widening investigation, and the courtroom verdict that turned one death into a national reckoning.

This episode traces how Koy’s death led investigators to a much larger pattern of suspected poisonings, why Thai police believed money and trust sat at the center of the case, and how the first major trial ended. On November 20, 2024, a Bangkok court convicted Sararat in Koy’s murder case and sentenced her to death in the first of multiple murder trials tied to the wider cyanide investigation.

As always, this story stays anchored to court reporting, verified news coverage, and the public record. Where rumor, online chatter, and public speculation enter the story, they are clearly separated from what can actually be proved. At the center of all of it is Koy, a woman whose life should never be reduced to a headline.

Two women.
Two suitcases.
Two bodies pulled from the quiet waters between Rayong and Chon Buri.

In early 2025, a fisherman in Rayong found a water-logged suitcase—inside, the decomposed remains of an unidentified woman. Seven months later, another case surfaced along the same stretch of coast, packed with dumbbells, iron chains, and another unnamed victim.

Were they both victims of one killer—or a pattern repeating itself?
This episode follows the real investigation, the verified facts, and the chilling precision that ties both murders together.

Based on reports from Khaosod English, Thai PBS World, The Pattaya News, and The Thai Examiner, along with statements from the Royal Thai Police.

Si Ouey, also known as Si Quey, remains one of Thailand’s most infamous true crime figures — a Chinese migrant laborer linked most directly to the 1958 Rayong child murder of Somboon Bunyakan, then transformed by tabloids, fear, and folklore into Thailand’s “cannibal killer” boogeyman.

In this episode of Shadows of Siam, we follow the strongest verified spine of the case: the Rayong killing, the wider disputed allegations, the anti-Chinese climate of the era, the public display of Si Ouey’s body at Siriraj, the removal of the “cannibal” label in 2019, and his cremation in 2020 after decades behind glass.

This is a Thailand true crime story about murder, myth, xenophobia, memory, and the danger of letting repetition harden into truth. If you care about Southeast Asia history, Thai crime cases, disputed convictions, and the stories behind national folklore, this one stays with you.

He stood for his people, and vanished into the forest he tried to protect.
In 2014, Karen activist Porlajee “Billy” Rakchongcharoen was detained by park officials inside Thailand’s Kaeng Krachan National Park—and never came home.
What followed would expose the country’s deepest fault line: the fight between conservation, corruption, and the right to exist.

This episode traces Billy’s disappearance, the discovery of burned remains in a hidden oil drum, and a courtroom battle that redefined Thailand’s human-rights landscape.

Thai serial killer Somkid Pumpuang, known in Thai media as Thailand’s Jack the Ripper, was released early after convictions in the 2005 murders of five women—then was accused of killing Ratsami Mulichan in Khon Kaen in 2019.

In October 2016, Bangkok woke to fear.
Three bodies in two days—bound, stabbed, and left in the dark corners of the city.
Police soon realized someone was hunting the homeless.
His name was “Jimmy,” a 20-year-old drifter from Myanmar whose quiet existence hid a brutal truth.

Across Bangkok and Pathum Thani, five people would die—four confirmed by DNA, one never officially named.
No motive. No confession. Only a trail of blood, a bicycle, and a city that barely noticed its own victims.

This episode follows the investigation that revealed one of Thailand’s most haunting modern crimes—when violence struck those already invisible.

🎧 Shadows of Siam tells the stories Thailand tries to forget—real cases of murder, mystery, and memory.

After moving her bed to face the closet mirror, a 23-year-old student in Chiang Mai began to notice strange things—whispers at night, shadows that only appeared in the glass, and a reflection that blinked... wrong.

In Thai culture, mirrors aren’t just reflective surfaces. They’re thresholds—especially dangerous when placed across from the bed.

This episode explores the chilling true account of Lila, a Thai-German exchange student, and the supernatural descent that followed a simple shift in furniture.
With insights from spiritual forums, Buddhist monks, and Thai real estate discussions, we uncover a belief rooted deep in Southeast Asian tradition—and what happens when it’s ignored.
